IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 206,918, dated August13, 187 8; application filed June 20, 1878.

To all whom it may concern:

Be it known that I, LEWIS J. ATWOOD, of Waterbury, in the county of NewHaven and State of Connecticut, have invented an Improvement inLanterns, of which the following is a specification:

Lanterns have been made with a glass and its frame connected to the baseof the lantern by bayonet-locking studs and slots.

One feature of my invention relates to a peculiar construction ofbayonet-lock at the edge of the air-distributer.

The top of the lantern has been detachable from the glass, and metallictops to lanternehimneys have been held in place by springs, a; i; myPatent No. 129,509, granted July 16, 1 7

Another feature of improvement in my present lantern relates to aspring-bail that serves the twofold purpose of holding the glass andmetallic top in place and of suspending the lanitern by a chain or ringconnected to such In the drawings, Figure 1 is a vertical section of thelantern. Fig. 2 is a plan of the same. Fig. 3 is a sectional plan of thebayonet-lock. Fig. 4 is a section of the burner detached, and Fig. 5 isan elevation of the lower part of the chimney-holder.

The reservoir a receives the base b of the burner. c is the wick tube;d, the air-distributer around the base, adjacent to the ratchet-cap. fis a supplemental air distributer surrounding the wick-tube, and havinga flat or nearly flat upper surface and conical sides, which areperforated with numerous holes. This is removable from theair-distributer d, but when in use it rests upon such airdistributer,and is held by tongues 2 2 that pass through mortises in suchair-distributor. The plates h are fastened upon the conical sides of thesupplemental air-distributer f, and stand at an inclination toward eachother, so that their upper ends are near each other above the wick-tube,and serve to direct air upon the flam'e. There are holes through thesedeflecting-plates h.

The edge of the airdistributer is turned up as a flange, 3, andcontracted at the upper part to form a nearly-semicircular recess, andthe ring I of the chimney or glass holder sits within this flange 3, andit is provided with ribs 5 at opposite sides, formed by striking up themetal in a die. Such ribs lit the semicircular recess of the flange 3,and this flange 3 is removed or notched at 4, so that the ring l can beset within the flange 3, one of the ribs 5 being set beneath therecessed edge of the flange 3, and the other rib being entered at thisnotch, so that the parts will be securely connected by giving the ring Ia partial revolution. The reverse motion separates thispeculiarly-constructed bayonet-lock.

The glass at rests upon this ring I, and its base-flange passes into thesame, and there is a metal cap, a, resting upon the top of this glass.

The spring-bail 0 is fastened securely at the bottom end to this ring I,and the upper end crosses above the cap a and rests within the groove ofthe same, and there is a loop or ring bent in the wire or secured to thesame at the center of the bail for the reception of a chain or hoop forsuspending the lantern. Guard-rings may be added to the bail o.

In placing the parts together the metal top is set upon the glass, andthen the glass is placed upon the ring I and the bail sprung over thetop of the lantern, or it is removed by a reverse motion. The bail-wire,not being straight, and bearing at the central part upon the cap 12, hassufficient spring to allow of this being done; and hence any specialprovisions of catches or looking devices for holding the glass to theframe are dispensed with.

I am aware that a stationary wirehas been used to hold the glass inplace, the base upon which the glass rests being made to rock as theglass is entered or removed.

I claim as my invention- 1. The spring-bail 0, attached rigidly at itslower end to the ring 1, upon which the glass m rests, in combinationwith said glass m and cap 12, in which cap is a recesss for the theair-distributer d, the removable supplespring-bail o, as and for thepurposes set mental air-distributerf, deflecting-plates h, forth. ringI, and glass m, substantially as set forth. 2. The recessed flange 3around the edge of Signed by me this 15th day of June, 1878. theair-distribnter, notched, in combination L. J.
